MIXING VALVE USAGE
This appliance has been design certi ed as complying with
American National Standard/CSA Standard for water heaters
and is considered suitable for:
Water (Potable) Heating and Space Heating: All models are
considered suitable for water (potable) heating and space heat-
ing.
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will satisfy space heating, clothes wash-
ing, dish washing, and other sanitizing needs can scald and
permanently injure you upon contact. Some people are more
likely to be permanently injured by hot water than others. These
include the elderly, children, the in rm, or physically/mentally
handicapped. If anyone using hot water in your home ts into
one of these groups or if there is a local code or state law requir-
ing a certain temperature water at the hot water tap, then you
must take special precautions. In addition to using the lowest
possible temperature setting that satis es your hot water needs,
a means such as a *Mixing Valve, should be used at the hot
water taps used by these people or at the water heater. Mix-
ing valves are available at plumbing supply or hardware stores.
Consult a Quali ed Installer or Service Agency. Follow mixing
valve manufacturer’s instructions for installation of the valves.
Before changing the factory setting on the thermostat, read the
“Temperature Regulation” section in this manual.

FACTS TO CONSIDER ABOUT THE LOCATION
Carefully choose an indoor location for the new water heater,
because the placement is a very important consideration for the
safety of the occupants in the building and for the most eco-
nomical use of the appliance. This water heater is not for use in
manufactured (mobile) homes or outdoor installation.
Whether replacing an old water heater or putting the water heater
in a new location, the following critical points must be observed:
1. Select a location indoors as close as practical to the vent
terminal or location to which the water heater vent piping is
going to be connected, and as centralized with the water pip-
ing system as possible.
2. Selected location must provide adequate clearances for ser-
vicing and proper operation of the water heater.
Installation of the water heater must be accomplished in such a
manner that if the tank or any connections should leak, the ow
will not cause damage to the structure. For this reason, it is not
advisable to install the water heater in an attic or upper oor.
When such locations cannot be avoided, a suitable drain pan
should be installed under the water heater. Drain pans are avail-
able at your local hardware store. Such a drain pan must have
a minimum length and width of at least 2 in. (51mm) greater that
the water heater dimensions and must be piped to an adequate
drain. The pan must not restrict combustion air ow.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage may
result in property damage, even with the use of a drain pan piped
to a drain. However, unanticipated damage can be reduced or
prevented by a leak detector or water shut-off device used in
conjunction with a piped drain pan. These devices are available
from some plumbing supply wholesalers and retailers, and de-
tect and react to leakage in various ways:
Sensors mounted in the drain pan that trigger an alarm or
turn off the incoming water to the water heater when leakage
is detected.
Sensors mounted in the drain pan that turn off the water sup-
ply to the entire home when water is detected in the drain
pan.
Water supply shut-off devices that activate based on the wa-
ter pressure differential between the cold water and hot water
pipes connected to the water heater.
Devices that will turn off the gas supply to a gas water heater
while at the same time shutting off its water supply.
Also, the water heater must be located and/or protected so it is
not subject to physical damage by a moving vehicle.
This water heater must not be installed directly on carpeting.
Carpeting must be protected by metal or wood panel beneath
the appliance extending beyond the full width and depth of the
appliance by at least 3 in. (76mm) in any direction, or if the ap-
pliance is installed in an alcove or closet, the entire oor must be
covered by the panel. Failure to heed this warning may result
in a re hazard.
LOCATING THE NEW WATER HEATER
9
INSULATION BLANKETS
Insulation blankets available to the general public for external use
on gas water heaters are not necessary with this product. The
purpose of an insulation blanket is to reduce the standby heat
loss encountered with storage tank water heaters. Your Water
heater meets or exceeds the National Appliance Energy Conser-
vation Act standards with respect to insulation and standby loss
requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions (See Figure 1 for identi ca-
tion of components mentioned below). Failure to follow these
instructions can restrict the air ow required for proper combus-
tion, resulting in re, asphyxiation, serious personal injury or
death.
Do not cover the outer door, thermostat or temperature &
pressure relief valve.
Do not cover the instruction manual. Keep it on the side of
the water heater or nearby for future reference.
Do obtain new warning and instruction labels from the manu-
facturer for placement on the blanket directly over the exist-
ing labels.
VENTILATION FOR APPLIANCES LOCATED IN
CONFINED SPACES
FIGURE 3
Con ned Space is a space whose volume is less than 50 cubic
feet per 1,000 Btu per hour (4.8 cm per kW) of the aggregate
input rating of all appliances installed in that space.
VENT TERMINATION
Before installing water heater determine placement of vent ter-
mination.
Make certain to observe vent location limitation, see Figures 3,
4 & 11.
Minimum clearances between the water heater
and combustible and noncombustible construction are: 0 in.
(0mm) from sides, 0 in. (0mm) from back, 4 in. (102mm) from
front of jacket to closet door and 20 in. (508mm) from top of
jacket to combustible and noncombustible material. Minimum
vent clearance: 1 in. (25mm)*. Provide 3 ft. (915mm) front clear-
ance for servicing and adequate clearance between the jacket
top & ceiling for servicing the ue area, see Figure 4.
* Where the wall is combustible and the wall thickness is over
14 in. (356mm), 1 in. (25mm) clearance to combustible materials
around the vent terminal is needed. The rst 14 in. (356mm) is
zero clearance.
Make certain the vent locations comply with the National Fuel
Gas Code ANSI Z223.1/NFPA 54 and/or local codes. There is
some important information shown in Figure 11.
For a second or more direct vent unit, the distance between vent
terminals must be a minimum of 12 in. (305mm).

be certain all parts of the venting system, as listed below,
are present. CAUTION!!! IF THERE ARE ANY DAMAGED
PARTS, DO NOT INSTALL THIS WATER HEATER. REPORT
ANY SHORTAGE TO YOUR DISTRIBUTOR OR DAMAGE TO
YOUR CARRIER.
GENERAL
The installation must conform to these instructions and the lo-
cal code authority having jurisdiction. In the absence of local
codes, the installation must comply with the current editions of
the National Fuel Gas Code ANSI Z223.1/NFPA 54. The code is
available from the Canadian Standards Association, 8501 East
Pleasant Valley Road, Cleveland, OH 44131.
WATER PIPING
HOTTER WATER CAN SCALD:
Water heaters are intended to produce hot water. Water heated
to a temperature which will satisfy space heating, clothes wash-
ing, dish washing, cleaning and other sanitizing needs can scald
and permanently injure you upon contact. Some people are
more likely to be permanently injured by hot water than others.
These include the elderly, children, the in rm, or physically/men-
tally handicapped. If anyone using hot water in your home ts
into one of these groups or if there is a local code or state law
requiring a certain temperature water at the hot water tap, then
you must take special precautions. In addition to using the low-
est possible temperature setting that satis es your hot water
needs, a means such as a *mixing valve, should be used at the
hot water taps used by these people or at the water heater, see
Figure 2. Valves for reducing point of use temperature by mixing
cold and hot water are also available:
Consult a Quali ed Installer or Service Agency. Follow man-
ufacturer’s instructions for installation of the valves. Before
changing the factory setting on the thermostat, read the “Tem-
perature Regulation” section in this manual.
This water heater shall not be connected to any heating systems
or component(s) used with a non-potable water heating appli-
ance.
All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall
not be introduced into this system.
When the system requires water for space heating at tem-
peratures higher than required for domestic water purposes, a
tempering valve must be installed. Please refer to Figure 2 for
suggested piping arrangement.
Water supply systems may, because of such events as high line
pressure, frequent cut-offs, the effects of water hammer among
others, have installed devices such as pressure reducing valves,
check valves, back ow preventers, etc. to control these types of
problems. When these devices are not equipped with an internal
by-pass, and no other measures are taken, the devices cause
the water system to be closed. As water is heated, it expands
(thermal expansion) and closed systems do not allow for the
expansion of heated water.
The water within the water heater tank expands as it is heated
and increases the pressure of the water system. If the relieving
point of the water heater’s temperature-pressure relief valve
is reached, the valve will relieve the excess pressure. The
temperature-pressure relief valve is not intended for the
constant relief of thermal expansion. This is an unacceptable
condition and must be corrected.
It is recommended that any devices installed which could create
a closed system have a by-pass and/or the system have an ex-
pansion tank to relieve the pressure built by thermal expansion
in the water system. Expansion tanks are available for ordering
through a local plumbing contractor. Contact the local water
supplier and/or a service agency for assistance in controlling
these situations.
NOTE: To protect against untimely corrosion of hot and cold
water ttings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
All gas piping must comply with local codes and ordinances or
with the National Fuel Gas Code ANSI Z223.1/NFPA 54 which-
ever applies. Copper and brass tubing and ttings (except tin
lined copper tubing) shall not be used.

Figure 5 shows the typical attachment of the water piping to the
water heater. The water heater is equipped with 3/4“ NPT water
connections.
NOTE: If using copper tubing, solder tubing to an adapter before
attaching the adapter to the cold water inlet connection. Do not
solder the cold water supply line directly to the cold water inlet.
It will harm the dip tube and damage the tank.
T & P VALVE AND PIPE INSULATION (IF SUPPLIED)
Remove insulation for T & P valve and pipe connections from
carton.
FIGURE 6
Fit pipe insulation over the incoming cold water line and the hot
water line. Make sure that the insulation is against the top cover
of the heater.
Fit T & P valve insulation over valve. Make sure that the insula-
tion does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
TEMPERATURE-PRESSURE RELIEF VALVE
This heater is provided with a properly certi ed combination
temperature - pressure relief valve by the manufacturer.
The valve is certi ed by a nationally recognized testing labora-
tory that maintains periodic inspection of production of listed
equipment of materials as meeting the requirements for Relief
Valves for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4,
and the code requirements of ASME.
If replaced, the valve must meet the requirements of local codes,
but not less than a combination temperature and pressure relief
valve certi ed as indicated in the above paragraph.
The valve must be marked with a maximum set pressure not to ex-
ceed the marked hydrostatic working pressure of the water heater
(150 psi = 1,035 kPa) and a discharge capacity not less than the
water heater input rate as shown on the model rating plate.
For safe operation of the water heater, the relief valve must not
be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly
into the tting of the water heater designed for the relief valve.
Position the valve downward and provide tubing so that any
discharge will exit only within 6 in. (152mm) above, or at any
12
distance below the structural oor. Be certain that no contact is
made with any live electrical part. The discharge opening must
not be blocked or reduced in size under any circumstances.
Excessive length, over 30 ft. (9.14m), or use of more than four
elbows can cause restriction and reduce the discharge capacity
of the valve, see Figures 5 or 10.
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
drain unless a 6 in. (152mm) air gap is provided. To prevent
bodily injury, hazard to life, or property damage, the relief valve
must be allowed to discharge water in quantities should circum-
stances demand. If the discharge pipe is not connected to a
drain or other suitable means, the water ow may cause property
damage.
The Discharge Pipe:
Shall not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
Shall not be plugged or blocked.
Shall be of material listed for hot water distribution.
Shall be installed so as to allow complete drainage of both
the temperature-pressure relief valve, and the discharge
pipe.
Shall terminate at an adequate drain.
Shall not have any valve between the relief valve and tank.
The temperature-pressure relief valve must be manually oper-
ated at least once a year. Caution should be taken to ensure that
(1) no one is in front of or around the outlet of the temperature-
pressure relief valve discharge line, and (2) the water manually
discharged will not cause any bodily injury or property damage
because the water may be extremely hot.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold water
inlet to the water heater, follow the draining instructions, and re-
place the temperature-pressure relief valve with a new one.
WATER (POTABLE) HEATING AND SPACE HEATING
1. All piping components connected to this unit for space heating
applications shall be suitable for use with potable water.
2. Toxic chemicals, such as those used for boiler treatment,
shall NEVER be introduced into this system.
3. This unit may NEVER be connected to any existing heating
system or component(s) previously used with a non-potable
water heating appliance.
4. When the system requires water for space heating at
temperatures higher than required for domestic water
purposes, a tempering valve must be installed, see Figure 7
for suggested piping arrangement.
FIGURE 7
CLOSED WATER SYSTEM
A closed system will exist if a back- ow preventer (check valve),
pressure reducing valve, or other similar device is installed in
the cold water line between the water heater and the street main
(or well). Excessive pressure may develop due to the thermal
expansion of heated water causing premature tank failure or
intermittent relief valve operation. This type of failure is not
covered by the limited warranty. An expansion tank may be
necessary in the cold water supply to alleviate this situation, see
Figure 1. Contact the local plumbing authority.
If the temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion
in a closed water supply system. Contact the water supplier or
local plumbing inspector on how to correct this situation. DO
NOT PLUG THE TEMPERATURE AND PRESSURE RELIEF
VALVE.
GAS PIPING
Make sure the gas supplied is the same type listed on the model
rating plate. The inlet gas pressure must not exceed 14 inch
water column (3.5 kPa) for natural and propane gas (L.P.). The
13
minimum inlet gas pressure shown on the rating plate is that
which will permit ring at rated input.
All gas piping must comply with local codes and ordinances or
with the National Fuel Gas Code ANSI Z223.1/NFPA 54 which-
ever applies. Copper and brass tubing and ttings (except tin
lined copper tubing) shall not be used.
If the gas control valve is subjected to pressures exceeding 1/2
psi (3.5 kPa), the damage to the gas control valve could result in
a re or explosion from leaking gas.
If the main gas line Shut-off serving all gas appliances is used,
also turn “off” the gas at each appliance. Leave all gas appli-
ances shut “off” until the water heater installation is complete.
A gas line of suf cient size must be run to the water heater.
Consult the current edition of National Fuel Gas Code ANSI
Z223.1/NFPA 54 and your gas supplier concerning pipe
size.
There must be:
A readily accessible manual shut off valve in the gas supply
line serving the water heater, and
A drip leg (sediment trap) ahead of the gas control valve to
help prevent dirt and foreign materials from entering the gas
control valve.
• A exible gas connector or a ground joint union between the
shut off valve and control valve to permit servicing of the
unit.
Be sure to check all the gas piping for leaks before lighting the
water heater. Use a soapy water solution, not a match or open
ame. Rinse off soapy solution and wipe dry.
When installed at elevations above 7,700 feet (2,347 meters), input
rating should be reduced at the rate of 4 percent for each 1,000 feet
(305 meters) above sea level which requires replacement of the
burner ori ce in accordance with National Fuel Gas Code ANSI
Z223.1/NFPA 54. Contact your local gas supplier for further
information.
Failure to replace the standard ori ce with a high altitude ori ce
when installed could result in improper and inef cient operation
of the appliance, producing carbon monoxide gas in excess of
safe limits, which could result in serious injury or death. Contact
your gas supplier for any speci c changes which may be re-
quired in your area.
Use pipe joint compound or te on tape marked as being resis-
tant to the action of petroleum [Propane (L.P.)] gases.
The appliance and its gas connection must be leak tested before
placing the appliance in operation.
The appliance and its individual Shut-off valve shall be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressures in excess of 1/2 pound per square inch
(3.5 kPa). It shall be isolated from the gas supply piping system
by closing its individual manual Shut-off valve during any pres-
sure testing of the gas supply piping system at test pressures
equal to or less than 1/2 pound per square inch (3.5 kPa).
Connecting the gas piping to the gas control valve of the water
heater can be accomplished by either of the two methods shown
in Figures 8 and 9.
FIGURE 8 GAS PIPING WITH
FLEXIBLE CONNECTOR.
FIGURE 9 GAS PIPING WITH ALL
BLACK IRON PIPE TO GAS CONTROL.
14
SEDIMENT TRAPS
A sediment trap shall be installed as close to the inlet of the
water heater as practical at the time of water heater installation.
The sediment trap shall be either a tee tting with a capped
nipple in the bottom outlet or other device recognized as an ef-
fective sediment trap. If a tee tting is used, it shall be installed
in conformance with one of the methods of installation shown in
Figures 8 and 9.
Contaminants in the gas lines may cause improper operation of
the gas control valve that may result in re or explosion. Before
attaching the gas line be sure that all gas pipe is clean on the in-
side. To trap any dirt or foreign material in the gas supply line, a
drip leg (sometimes called a sediment trap) must be incorporat-
ed in the piping. The drip leg must be readily accessible. Install
in accordance with the “Gas Piping” section. Refer to the current
edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54.

FILLING THE WATER HEATER
Never use this water heater unless it is completely full of water.
To prevent damage to the tank, the tank must be lled with water.
Water must ow from the hot water faucet before turning “ON”
gas to the water heater.
To ll the water heater with water:
1. Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
2. Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open when
the water heater is in use.
3. To insure complete lling of the tank, allow air to exit by open-
ing the nearest hot water faucet. Allow water to run until a
constant ow is obtained. This will let air out of the water
heater and the piping.
4. Check all water piping and connections for leaks. Repair as
needed.
VENTING
NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO
THE OUTDOORS AND HAS ADEQUATE AIR SUPPLY TO
AVOID RISKS OF IMPROPER OPERATION, FIRE, EXPLOSION
OR ASPHYXIATION.
DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND
VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION
AND VENTILATION MUST BE PROVIDED FOR SAFE
OPERATION.
HIGH ALTITUDE INSTALLATIONS
Installations above 7,700 ft. (2347 m) require replacement of the
burner ori ce in accordance with the National Fuel Gas Code
ANSI Z223.1/NFPA 54. Failure to replace the ori ce could result
in improper and inef cient operation of the appliance, producing
carbon monoxide gas in excess of safe limits, which could result
in serious personal injury or death. Contact your gas supplier for
any speci c changes which may be required in your area.

TEMPERATURE REGULATION
TEMPERATURE REGULATION
HOT WATER CAN SCALD: Water heaters are intended to
produce hot water. Water heated to a temperature that will
satisfy space heating, clothes washing, dish washing, and other
sanitizing needs can scald and permanently injure you upon
contact. Some people are more likely to be permanently injured
by hot water than others. These include the elderly, children, the
in rm, or physically/mentally handicapped. If anyone using hot
water in your home ts into one of these groups or if there is a
provincial, state law or local code requiring a speci c hot water
temperature at the tap, then you must take special precautions.
Never allow small children to use a hot water tap, or to draw
their own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
It is recommended that lower water temperatures be used to
avoid the risk of scalding. It is further recommended, in all cases,
that the water temperature be set for the lowest temperature that
satis es your hot water needs. This will also provide the most
energy ef cient operation of the water heater.
Figure 29 shows the approximate water temperatures produced
at various thermostat dial settings. Short repeated heating
cycles caused by small hot water uses can cause temperatures
at the point of use to exceed the thermostat setting by up to 30°F
(17°C). If you experience this type of use you should consider
using lower temperature settings to reduce scald hazards.
Valves for reducing point-of-use temperature by mixing cold
and hot water are available (see Figures 2 & 7). Also available
are inexpensive devices that attach to faucets to limit hot water
temperatures. Contact a licensed plumber or the local plumbing
authority.
SHOULD OVERHEATING OCCUR OR THE GAS SUPPLY FAIL
TO SHUT OFF, TURN OFF THE MAIN MANUAL GAS CON-
TROL VALVE TO THE APPLIANCE (SEE FIGURE 1).
NOTE: A water temperature range of 120°F-140°F (49°C-60°C)
is recommended by most dishwasher manufacturers. The ther-
mostat of this water heater has been factory set at its lowest
position (PILOT LIGHTING). It is adjustable and must be reset
to the desired temperature setting to reduce the risk of scald
injury. The mark ( ) indicative of approximately 120°F (49°C)
is preferred starting point. Some provinces may have a require-
ment for a lower setting.
Turn the water temperature dial clockwise ( ) to decrease the
temperature, or counterclockwise ( ) to increase the tempera-
ture.
